Interface ZipExtraField

All Known Implementing Classes:
AsiExtraField, JarMarker, UnrecognizedExtraField

public interface ZipExtraField

General format of extra field data.

Extra fields usually appear twice per file, once in the local file data and once in the central directory. Usually they are the same, but they don't have to be. java.util.zip.ZipOutputStream will only use the local file data in both places.


Method Summary
 byte[] getCentralDirectoryData()
          The actual data to put central directory - without Header-ID or length specifier.
 ZipShort getCentralDirectoryLength()
          Length of the extra field in the central directory - without Header-ID or length specifier.
 ZipShort getHeaderId()
          The Header-ID.
 byte[] getLocalFileDataData()
          The actual data to put into local file data - without Header-ID or length specifier.
 ZipShort getLocalFileDataLength()
          Length of the extra field in the local file data - without Header-ID or length specifier.
 void parseFromLocalFileData(byte[] data, int offset, int length)
          Populate data from this array as if it was in local file data.
